Nothing, and that may be a reasonable first approximation.
Long term we should note that while "=m" does require the
original address, the contents are killed, and thus the old
value is dead. Similarly, while "m" requires the original
address, the contents are *not* killed.
I wonder if GIMPLE needs better annotations on parameters?
In particular, I recall that Ada can explicitly set in, out
or inout in the source code.
